Endogenous variables are important in econometrics and economic modeling because they show whether a variable causes a particular effect. Economists employ causal modeling to explain outcomes (dependent variables) based on a variety of factors (independent variables), and to determine to which extent a result can be attributed to an endogenous or exogenous cause.
'''Exogenous''' (or exogeneous) (from the [[wiki/Greek language|Greek]] words "exo" and "genis", meaning "outside" and "generated") refers to an action or object coming from outside a system. It is the opposite of [[wiki/Endogenous|endogenous]], something generated from within the system.
Endogenous variable is a variable which used in economics for inner side parameters and accelerator coefficient of movement. andExogeneous is outside parameters as taxation,tariff,govt revenues e.t.c
1-Endogenous antigens(En.A) originate by the multiplication of pathogen inside the antigen presenting cell, such as pathogen is intracellular multiply in cytoplasm. 2-En.A presented via M.H.C1 molecule recognized by the CD8 and T-lymphocytes. 3-It includes viral and tumor antigens. 1-Exogenous antigens (Ex.A) originates outside and taken by antigen presenting cells when extracellular pathogen are engulfed and kill inside the phagolysosome. 2-Ex.A presented via M.H.C2 molecule recognized by CD4 and T-Lymphocytes. 3-It includes allergens,bacteria structures (like capsule, flagella e.t.c).
a variable changes a rule doesnt.
They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!
The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.

Endogenous is internal, biological and somatic Exogensous is externally caused - environmental
Endogenous disease is when the cause is within the body and not outside the body.(eg. appendicitis) Exogenous disease has trigger source outside the body. (eg. infections)

Any activity which is occurring outside the system ,and that particular activity also affect the system is known as exogenous activity whereas endogenous activity are those activity that occur within the system ,and also affecting the system.

The distinction between these two types of variables is whether the variable regress on another variable or not. Like in a linear regression the dependent variable (DV) regresses on the independent variable (IV), meaning that the DV is being predicted by the IV. Within SEM modelling this means that the exogenous variable is the variable that another variable regresses on. Exogenous variables can be recognized in a graphical version of the model, as the variables sending out arrowheads, denoting which variable it is predicting. A variable that regresses on a variable is always an endogenous variable even if this same variable is used as an variable to be regressed on.
The basic difference is that exogeneous variables are fully determined outside the system, but predetermined variables are not. Think of an equation where you have some lagged variables that are independent of subsequent error terms (e.g.consumption in the current period depends on some functional that includes the consumption of the previous period). We could say that the lagged variable was already determined in the period before. Asymptotically predetermined variables can be treated as exogeneous.
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
Type II hypersensitivity is also known as cytotoxicity hypersensitivity and it may affect variety of organs and tissues. The antigens are endogenous and exogenous chemicals. Type III Hypersensitivity complex type of hypersensitivity and it may affect individual organs like skin, Liver etc.
